Abstract

Seed bacterization bl Pseudomonas fluorescens and P. aeruginosa alone and in combination with aerial spray of their cell suspensions or Neemazal, a produce of neem (Azadirachta indica), at different concentrations was tried under field conditions to control powdery mildew (Erysiphe pisi) of pea (Pisum sativum) through induced resistance in the host. Combination of seed bacterization with tither aerial sprays of bacterial cell suspensions or Neemazal was more effective in controlling the disease at all concentrations ofNeemazal (50 mg/l being the optimum) than seed bacterization alone. Bacterization by both bacteria, and aerial spray of Neemazal increased the dry weight of aerial parts, number of nodes and pods as well as seed weight of pea planes. Colonization of the rhizosphere and rhizoplane was maximum by P. aeruginosa followed by strain Pf5 of P. fluorescens . The lower most leavessupported better survival of these two plant growth-promoting rhizobacteria (PGPR) than the upper leaves.
